WILLIAM HOOKER, OF SOUTH MELBOURNE, VICTORIA, AUSTRALIA.

AUTOMATIC APPARATUS FOR SUPPLYING AIR FOR MANY PURPOSES.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed March 18, 1908. Serial No. 421,938.

To all whom it may concern:

Be it known that I, WILLIAM HOOKER, of 14 Moubray street, Albert Park,South Melbourne, in the State of Victoria, Commonwealth of Australia, asubject of the King of Great Britain, have invented certain new anduseful Automatic Apparatus for Supplying Air for Many Purposes, of whichthe following is a specification.

This invention relates to an electrical apparatus for automaticallycharging and recharging a vertically-operated holder with air wheneverthe holder becomes nearly exhausted so that the air supply thus createdcan be used for many purposes, such as for instance, in the manufactureof petrol air gas, or in the ventilating of rooms. But in order that myinvention may be better understood I will now refer to the accompanyingsheet of drawings in which like letters represent like parts where theyoccur in the views.

Figure 1 is a side elevation of the appara- Fi 3 air valve arrangementusable instead of the water seal chamber hereinafter described.

In carrying out my invention I employ any suitable primary cell batteryA and place it in circuit with an electric motor (A and an electricswitch with handle (B).

The battery is arranged in the box (0) and the switch upon a studforming part of the framework (1)) provided for supporting theapparatus.

The motor (A carries the grooved pulley (E) upon its spindle (F) fordriving the endless belt or cord (G) and the crank driving wheel (H)which is carried by the horizontal shaft (I) suitably mounted inbearings secured to the bracket (J) projected from the frame post (K).(L) is a pitman or connecting rod the lower end of which is suitablyjointed with the lever handle (M) of the air bellows (M shown beneathsaid frame (N). (O) is an air delivery pipe communicating with theinterior of said bellows (M and the Water seal chamber (P) provided withthe draw oflt' cock (Q). (R) is also another air delivery pipe -lea-dingfrom said chamber (P) into the air holder (S) which moves verticallywithin the water tank (T). (U) is an outlet pipe arranged in said holder(S) and provided with the draw off cock (V).

This holder (S) has the arm (W) projected therefrom to operate thevertical rod (X the lower end of which is provided with an india rubberband or strap (X). This band or strap (X) is connected with the handle(B) of said switch which consists of two semi-circular shaped plates (Z)and (Z and the said switch handle for either making or breaking thecircuit between the electric motor (A and the battery (A). (Z is a guidestem fixed upon the dome of said holder (S) to pass through the crossbar of the frame (D).

In Fig. 3 (Z is an air disk valve, (Z casing for same, (Z open facevalve seat, (Y) circuit wires of electric battery, motor and switch.

The working of my apparatus is as follows :On starting, the switchhandle (B) is deflected or moved downwards across both of the switchplates (Z) and (Z so as to allow of the battery current passing into theelectric motor (A which now revolves and opcrates the driving belt (G)and crank driving wheel (II). By this means the connecting rod (L)reciprocates the lever handle (M) and pumps air from the bellows (Mthrough pipe (O) to the water seal chamber (P) thence through pipe (R)and into the holder (S) from which it can be drawn off through the cock(V) and used for the desired purpose. As the holder (S) is filled withthe air it ascends by the pressure of air introduced carrying with itthe arm (W) and rod (X and as it reaches the limit of its travel theswitch handle (B) is drawn across the switch plates (Z) and (Z therebycutting off the electric current and causing the motor to cease working.On the other hand as the air is drawn from the holder (S) through theoutlet pipe (U) for the purpose required said holder gradually descendsand on approaching its lowest limit the switch handle (B) is moved to anopposite direction thereby establishing the circuit and again settingthe motor in action for the further pumping of air into the holder (S).

In lieu of the water seal chamber (P) I may substitute the air valve (Zshown at Fig. 3 in which case communication between the bellows (M andthe air holder (S) would be the same.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is An automatic air forcing apparatuscomprising a stand, a bellows beneath the same,
